我有以下设置:
$handle = curl_init();
curl_setopt($handle, CURLOPT_URL, $url);
curl_setopt($handle, CURLOPT_HTTPHEADER, $headers);
curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);
curl_setopt($handle, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($handle, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($handle, CURLOPT_TIMEOUT, 30);
curl_setopt($handle, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($handle, CURLOPT_POST, true);
curl_setopt($handle, CURLOPT_POSTFIELDS, $data);
$response = curl_exec($handle);
但是当请求被发送到当前根本没有响应的服务器时,curl 在 1 秒内返回应答。我不明白为什么会这样,因为我已将 CURLOPT_CONNECTTIMEOUT 设置为 30,这应该意味着 curl 轮胎连接到服务器 30 秒。我需要 curl 尝试连接 30 秒,这不是 CURLOPT_CONNECTTIMEOUT 应该做的,还是有某种误解?
这是 print_r(curl_getinfo($handle), true) 返回的内容:
